"Brutus' love to Caesar was no less than his" (3. 2. 61) This is ethos because Brutus is trying to establish his own credibility in saying that he loved Caesar just as much as the next person did.
"Who is here so vile that will not love his country?" (3. 2. 61) This is pathos because Brutus is trying to make the citizens feel guilty if they thought that killing Caesar was wrong. He is trying to invoke feelings of guilt.
"Had you rather Caesar were living and die all slaves, than that Caesar were dead, to live all free men?" (3. 2. 61) This is logos because he is trying to use logic and make the citizens think that they would rather be free without Caesar than be "slaves" with Caesar still alive.
